CDH uses a two-week average of daily COVID-19 cases calculated per 100,000 people in a given county. The categories areweekly assessments of community spread and are updated on Mondays. They are recommendations only; final decisions aremade by local school boards. If category designations are adjusted, then schools and families should expect transition timeas changes may or may not be immediate.

Private and charter schools should use the category based on the address of their facility and associated school districtboundary. Corresponding data is updated every Monday by noon on CDH's Tableau Page. See the respective countytab for related data.

= 20.75 for the 2-week average rate / Red Category

Possible Differences for Rural CommunitiesCDH recognizes the potential for community spread differences within its ruralcounties of Boise, Elmore, and Valley, and the role that geographic distance mightplay in a community’s risk. For instance, Basin School District and Horseshoe BendSchool District are both located in Boise County, but are approximately 30 milesapart and an hour’s drive. Because of the significant geographic distance, it ispossible that two school districts within the same county could, at times, be indifferent risk categories. CDH will work directly with the school districts andindependent schools if this situation arises.
